FRP SQUARE TUBE
process custom-made frp pultruded square tube profile
The company has more than 20 years of design and production experience, according to customer drawings, physical and open-mold production requirements.
frp pultruded square tube profile is a new type of composite material, which has the advantages of light weight, high strength, anticorrosion, heat preservation, insulation, sound insulation, long service life and so on. Glass Fiber Reinforced Plastic (FRP) is a good corrosion-resistant material. It has good resistance to atmosphere, water, acid, Alkali, salt, oil and solvent. General FRP profiles can not be used for a long time at high temperature, the strength of general-purpose Polyester FRP is obviously decreased above 50 °C, and that of general-purpose Epoxy FRP is obviously decreased below 100 °C and above 60 °C. According to different corrosion environment, different anti-corrosion resins can be selected, including: unsaturated polyester resin, vinyl resin, bisphenol a resin, epoxy resin and Furan Resin, etc. , for Acidic Environment, bisphenol a resin, Furan Resin, etc. ; for alkaline environment, Vinyl Resin, epoxy resin, Furan Resin, etc. ; for solvent environment, Furan Resin, etc. When acid, salt, solvent and so on corrosion is not very serious, then may choose the relatively low price isophthalic resin. By selecting different resin, frp profiles can be widely used in acid, Alkali, salt, solvent and other working environment, showing good corrosion resistance.
